COMBINATION THERMOMETER GAS ING A? i i I 2 Inventor William C. Zaz'lqy z mwm Patented Apr. 18 1933 WILLIAM c. BAILEY, or Los ANGELES, onnrnonnm A commnnrron rnnnnomnrnaoiasme Application filedctober16, 1931.-' SerialNo.569,299. i

This invention relatesto casings for'ther V Longitudinally slidablejin theother the j V mometers, and the primary object ofthe invention is to provide a casing for accommodating the thermometer especially clinical thermometers when the same is not in use,

together with means forrestoring the-then,

mometer to its original .low reading.

A still further object of the inventionis to provide means for subjecting clinical thermometer to the action .of centrifugal force for restoring the original low reading of the thermometer. t 3 j '1 :Other objects and advantages of the invention will become apparent from a study:

of the following description,taken in connection with the accompanying drawings wherein:

Figure 1 is an elevational view of the dea with inner and; outer collars'19 whereby the a. shaft is supported in arotatable manner.

vice.- a V a a Figure 2 is a'topplan view thereof. Figure 3 1s a bottom plan view thereof; Figure 4 1s a longltudlnal sectional taken on the line44 ofFigure 2. a

Figures 5 and 6 are'transverse sectional; views taken substantially one-the lines 5-5 and 6+6 respectively of Figure 4. t

Figure 7 is a perspective view ofa spring. clip. r t

Figure 8 is a fragmentary sectional elevational view of the upper portions of a tube and spirally grooved shaft forming a part of the means for returning the thermometer to original low reading. i With reference more in detail to the draw- 5 ings, it will be seen that the invention has as its preferred embodiment thereof, and as shown, comprises a shell like casing 5 formed of suitable material, and of suitable dimensions. Casing 5 is provided into two compartments elongated longitudinally through the medium of a partition 6. In one of the compartments, for example the compartment 7, there is provided a body 8 constituting a thermometer holder and provided with a 10. To retain the thermometer 10 within the bore of the holder 8 there is provided for said K holder a catch 11 that is screw threadedly engaged to one end of the holder 8 as at 12.

'by any suitable fastening elementto the outer;

longitudinal bore 9 for accommodating athfoiigh th m di m f a Spring conventional type of clinical thermometer compartments namely the compartment 13 isa tube 14 closed at onej enid having said one endnormally extending through the wall of the casing 5 atj'the corresponding end; of the casing. Atits inneropen end, the tube 14 is flared outwardly as at 15 and the flared end '15 isp'rovided with a notch ltrengaging a mote from the closed end of the tube 14,; i

Theextended end of the shaft 18is provided, 1

A spring clip 20 comprises a longitudinally split tubular body portion-at one end merging intoan'attaching plate2l that is: secured end of shaft 18 as clearly; suggested inthe drawings. The tube 20is adapted to receive in fixedcylindrical portion thereof oneend of the thermometer 1 0 ,so asato-rotatefthis shaft 18 :by "action of centrifugal force the I mercury in the] thermometer will be shift- 8 ed to, return to the originalor normal low reading-1, '1 i, v

. As shown to advantage Figure tube 14 is normally urgedginwardlyof; the.

24 normally urged inwardly of the tube 1 When rthe' parts fare in theirnormal position that is inth'e position shown-in Figure 4, the beveled free end of the dog 24fengages a; circumferentially extending groove "26 provide'dw atthe upper end of the-shaft 18; Gomcompartment 13 through the mediumL of a municating with the groove 26 is the upper end of a spiral groove 27 that extends fromv the groove 26 to the lowermost end of the shaft 18.

' Now assuming, that the clinical thermometer 10 has been used, for a purpose apparent,

the doctor or attendant places thethermom eter in the lip 20, and grasping the outer end i of the tube 14 with one hand pulls on the tube against the action v of the spring, 28,

whereby thedog '24 and groove 26' will move into the spiral groove 27 causing the shaft -18 to rotate at suficient speed, as to cause the mercury inthe tube by centrifugal force to be shifted forr-eturning to its normal or low reading position;

- o Upon-release. of the tube 14, the same un der action of spring 25 will move inwardly of the casing 5 and obviously the dog 24, when thetube has returned to its normal position, will reengage groove 26." I

In placing; the thermometer in the spring clip or holder 20, care should be taken to push the top or'upper end of the .thermometer through'the cylindrical portion of the clip to a position as near the'shaft aspossible, thrusting the mercury bulb of the thermometer as far as possible from the center of motion to obtain the best results;

After the thermometer has been returned to its 'origmal low reading, the same may I be moved from the clip 20 and then inserted in the bore of the holder8and the I 11 and threadedly engaged with the holder for maintaining the thermometer encased.

Even though I have herein'shown and described the preferred embodiment of the in vention,;it is to be understoodthat the same vis susceptibleof further changes, modifications andimprovements coming within the scope of the a iipendedclaims. V r Having thus described my inventiomwhat I'claimasnew is:

1. I A thermometer case comprising-in combination a pair of compartments, one of said compartments being adapted to contain a thermometer, a spirally threaded shaft rotatably mounted inthe'other of said com partments, normallyretracted means mew able longitudinally'of the last named compartments and: adapted for engagement with the spiral tread of said shaft to rotate the article holding clip connecting with said shaft and extending at right angles thereto.

3. In a thermometer case, a'compartment I,

elongated longitudinally, a. shaft rotatably mounted in said compartment, a tubular member receiving said shaft, inter-engaging means'on said tubular member and the wall 7 of said compartment to retain said tubular member against rotation, spring means normally urging said tubular member longitudinally in onedirection, and inter-engaging means on said tubular member and on said shaft for rotatin the latter'upon longitudinal shifting movement of the tubular mem- V I ber, and means for mounting a thermometer atright angles to said shaft.-

bination a rotatably mounted shaft,'a tubular member receiving the shaft and .con-' strained to" shift longitudinally thereof,. spring means engaged with the tubular member and normally urging the same to shift 4. A thermometer case compnsing in comlongitudinally in one direction, said shaft Y being provided with a spiral thread, anda pivoted pawl carried by saidtubular member and engaging said thread for rotating the; shaft upon shifting movement of the tubular member; and a springclip mounted on said shaft for holding a thermometer at right angles to the shaft;

5. In a device of the character described, a casing provided with two compartments, one ofwhi'ch is adapted to containfathermometer' and the other of whi ch is adaptedto contain a rotatable shaft,a. shaft in the latter 7 compartment equipped with means for engaging the'thermometer to retain the latter at an angle to the shaft, and means for To "tating the shaft for. subjecting the thermometer to centrifugal force for the purpose of restoring the original low reading of the ther mometer. v v

' In testimony whereof I affix my signature.
